The dollar enters Wednesday holding most of its June gains, and the reason is not subtle. The US struck Iran after Tuesday's market close, hours after President Trump suggested a deal could come within days. May CPI prints this morning at 8:30 AM ET. Between those two events sits every major FX pair.
What is driving dollar strength right now?
Rate differentials, mostly, with a geopolitical bid layered on top. The Fed sits at 3.50-3.75% with CME FedWatch pricing a 99.4% hold at the June 16-17 meeting and a 72% chance of at least one hike this year. The ECB is at 2.00%. The BOJ is at 0.75%, its highest in roughly 30 years but still 275 basis points below the Fed. The BOE sits in the 4.25-4.50% range after a series of measured cuts. Carry favours the dollar against everything except sterling, and sterling has its own problems.
Tuesday added the risk-off layer. The 10-year Treasury yield hit a 16-month high of 4.69%, the S&P 500 fell 0.26% to 7,386.65, and the Nasdaq dropped 0.97% as the chip rebound fizzled. Then came the strike on Iran after the close. Safe-haven dollar demand into a hot inflation print is a crowded but rational trade.
Where do the major pairs sit before CPI?
EURUSD trades near 1.1538 with non-commercial positioning 51.9% long per the latest COT data. That is a mild long bias into an event that could push the pair either way: a soft CPI weakens the dollar and the longs get paid, a hot print probably forces a test of 1.1450.
GBPUSD carries the heaviest speculative short in G10, with net non-commercial positioning at -51,483 contracts. Shorts this crowded are fuel. If sterling catches any bid, the squeeze does the work. Until then the rate gap and soft UK data keep the pressure on.
USDJPY closed at 160.15 on June 9, and this is where it gets interesting. Net speculative yen shorts sit at -136,611 contracts, roughly two-thirds of open speculative positioning. BOJ Governor Ueda said this week the bank should carefully weigh the costs and benefits of further hikes, and PM Takaichi told parliament the government wants to support the yen by strengthening the economy. That is the polite phase of verbal intervention. Crowded shorts above 160 with officials clearing their throats is a setup that has ended badly for carry traders before. The unwind trigger would be a hawkish BOJ surprise, not more easing.
AUDUSD holds a 62.6% long non-commercial bias, still riding the RBA's hawkish turn to 3.85%. CAD nets -93,256 short, which leaves room for a squeeze if US rates stabilise after the FOMC.
What does today's CPI print actually decide?
May CPI lands at 8:30 AM ET. April came in at 0.6% MoM and 3.8% YoY, the highest annual rate since May 2023, and most of it was energy. Consensus for May is roughly 0.3% MoM headline with core YoY expected near 2.8-2.9%.
The asymmetry matters more than the point estimate. A soft print gives Fed Chair Kevin Warsh room at his first dot plot on June 17 and probably takes some air out of the dollar. A hot print, especially with oil supply now back in question after the Iran strike, hardens the 72% hike probability into something closer to consensus and extends the dollar's run. One detail from Tuesday worth holding onto: the NFIB survey showed the share of small-business owners planning price increases at its highest in nearly four years. The inflation pipeline is not empty.
PPI follows on Friday June 12 at 8:30 AM ET. April PPI ran 1.4% MoM, the largest single-month advance since March 2022. The FOMC decision and dot plot land Wednesday June 17 at 2:00 PM ET, and June OPEX follows Thursday June 18, pulled forward from the Juneteenth holiday.
What is the VIX and yield curve actually signalling?
The VIX closed Monday at 18.92, then pushed back above 20 intraday Tuesday as the Iran headlines hit. Calling that "normal" would be generous. The rally that carried the S&P through nine straight winning weeks ran on a VIX of 12-16. The current regime is something else.
The curve is not flattening either. Long rates are rising faster than short rates, with the 10-year at 4.69% and the 30-year above 5%. That is a bear steepener, and historically it shows up when markets price persistent inflation rather than recovery. For FX it reinforces the dollar carry story. For equities it keeps the pressure on long-duration tech, which is exactly what Tuesday's failed chip bounce looked like.
What should FX traders actually watch this week?
Three things, in order. The CPI print at 8:30 AM ET today sets the dollar's direction into the FOMC. The official response from Iran determines whether the oil risk premium widens again, which feeds straight back into inflation expectations and the long end. And any escalation in BOJ language around the 160 level on USDJPY could turn the most crowded short in the market into the fastest unwind.
The dot plot on June 17 at 2:00 PM ET is the destination. Everything between now and then is positioning.
